INPPL1 (Phosphatidylinositol 3,4,5-trisphosphate 5-phosphatase 2) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Endometrial cancer. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Phosphatidylinositol (PtdIns) phosphatase that specifically hydrolyses the 5-phosphate of phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3) to produce PtdIns(3,4)P2, thereby negatively regulating the PI3K (phosphoinositide 3-kinase) pathways. Required for correct mitotic spindle orientation and therefore progression of mitosis. Plays a central role in regulation of PI3K-dependent insulin signalling, although the precise molecular mechanisms and signalling pathways remain unclear. While overexpression reduces both insulin-stimulated MAP kinase and Akt activation, its absence does not affect insulin signalling or GLUT4 trafficking. Confers resistance to dietary obesity. May act by regulating AKT2, but not AKT1, phosphorylation at the plasma membrane. Location: Cytoplasm, cytosol; Cytoplasm, cytoskeleton; Membrane; Cell projection, filopodium (UniProt). Locus 11q13.4 (HGNC).
